The CJK package for LaTeX

Welcome to CJK version 4.8.5 (16-Oct-2021), a LaTeX 2e macro package that enables the use of CJK scripts (Chinese/Japanese/Korean) in various encodings, written by Werner Lemberg.

This package is in maintenance mode; no new development will happen. Its use has become obsolete more or less – recent TeX engines like luatex, XeTeX or upTeX (which are all part of TeXLive) use Unicode natively and thus have far better support for CJKV languages.

A mailing list exists at; to subscribe; send a mail with the subject subscribe to Alternatively, a web interface can be found here.

If you are interested in the process of development you may observe the CJK git repository to see the code commitments, and which also provides snapshots.

The package comes in two parts:

cjk-4.8.5.tar.gz The source files.
cjk-4.8.5-doc.tar.gz Preformatted documentation files: DVI, PDF, output from cjk-enc.el, etc.

Note that on CTAN and its mirrors, the source archive is unpacked; you must thus get all files and subdirectories from language/chinese/CJK/.

An old article about the CJK package can be found in TUGBoat, volume 18, issue 3.

Recent changes to the CJK package can be found here.
